WebAPG100 SERIES ACTIVE PIRANI VACUUM GAUGES Edwards APG100 series Active Pirani vacuum gauges are available the standard model and measures a corrosion resistant version with Both gauges feature compact size for easy installation, a linear output, and a replaceable sensor tube. The Pirani gauge is a robust thermal conductivity gauge used for the measurement of the pressures in vacuum systems. It was invented in 1906 by Marcello Pirani. Marcello Stefano Pirani was a German physicist working for Siemens & Halske which was involved in the vacuum lamp industry. In … See more The Pirani gauge consists of a metal sensor wire (usually gold plated tungsten or platinum) suspended in a tube which is connected to the system whose vacuum is to be measured. The wire is usually coiled to make the gauge … See more A special form of the Pirani gauge is the pulsed Pirani vacuum gauge where the sensor wire is not operated at a constant temperature, but is … See more • • Jitschin, W.
